【摘要】 本文提出一个库仑滴定铀的新方法,样品经浓HCl和浓H₂So₄分解并用H₂O₂氧化其它价态的铀为六价。在6MH₂SO₄,0.1MTl⁺,0.5MTi⁴⁺底液中用铂网电极为工作电极,先后电生Ti³⁺和Tl³⁺以库仑回滴定法测定铀,对标准铀溶液滴定结果为,毫克量铀,误差在±0.1%以下,微克量铀,误差在+0.4%左右,样品分析结果与重量法相符,但测定快速的多。更多还原

【Abstract】 A new coulometric method for the determination of uranium with TI（111）-TL（111） biintermediate has been reported in this paper. The Uo₂⁺²in samples was first reduced by excess TI（111） electrogenerated,then the excess of TI（111） was oxidated by TL（111） electrogenerated in the 6M H₂SO₄, 0.1M TL at platinum electrode, and the content of uranium was obtained by calculation. The results of the coulometric titration for uranium in samples are consistant with those obtained by grawimetrie method.更多还原
